NAME
probenis - Probes for existence of NIS server
SYNOPSIS
/usr/sbin/probenis [-t timeout] domain
DESCRIPTION
The probenis command probes the network to determine whether or not NIS is available. Although part of the JOIN package, it does not
explicitly depend on the configuration database and can be used standalone. It is chiefly of use on nomadic machines to prevent the invo-
cation of ypbind on a network where NIS is unavailable.
It uses broadcast RPC to make a call to YPPROC_DOMAIN_NONACK, and then waits for a reply to be received or a timeout. Unless changed on
the command line, the default timeout for RPC is used (currently 25 seconds). The probenis command takes no action other than to set an
exit code: zero if NIS appears to be running, nonzero otherwise.
